Hey guys, I just wanted to ask those who own knives that have titanium liners, have your knives developed lock rock? I am looking to purchase a titanium liner lock knife but I am scared of it developing lock rock because I have a titanium frame lock that developed rock lock.
 
I have owned three titanium liner locks: TRM Atom, TRM Neutron, ABW Model 1 V4.

The ABW had to be sent back twice because the lock would slip and fail. Both of the TRMs have developed lock rock but I haven't gotten around to sending them back yet.

So far my confidence in titanium liner locks is extremely low, but that's not to say there aren't good ones out there.
 
I have three Benchmade AFCK's with titanium liner locks, one has seen a lot of use. They all lock up rock solid.

I have a Benchmade Darkstar with titanium liner lock. It's seen a lot of use. The lock can be made to flex under pressure, but it doesn't budge or move across the blade tang.

I have a Bradley Alias titanium frame lock (made by Benchmade). It's seen more use than any knife previously mentioned. After many years of use it's lockup is still rock solid.

The only titanium liner lock I've owned that had lock rock (a serious case) was a Lone Wolf T3. At $300 it was one of my biggest knife disappointments. I parted with that knife a long time ago.

It's usually pretty helpful if you list the actual brand and model of knife you're looking at. You will get much better feedback.

I only have one Ti liner lock, Emerson CQC-7 and it's fine.
 
It looks like everyone has a different experience, and to reply to Danke42, I am looking at a Spyderco Subvert and a CKF Decepticon, I half wish they were actually frame locks, when I am squeezing the life out of the frame lock during use it has never slipped, obviously with a liner lock I know we don't have that option.
 
My only ti linerlock is my TRM Atom. It does not have any issues with lock up, but I also do not use it for anything but light to medium slicing. It's by far my daintiest folder, but I knew that when I bought it.

I think most of us would be pretty happy with a Subvert.

My take on a liner lock is since it's a smaller contact point than a frame lock it's actually stronger than a frame lock. Just like lying on a bed of nails is fine but lying on one nail isn't much fun.
 
I've owned several Emersons with Ti liner locks, plus one Southern Grind, and never had any issues. Two of those Emersons were my EDCs for several months each.

I don't know that I'd want a flipper with Ti liners, but Ti liner locks have yet to be a problem for me on knives I slow-roll open.
 
I own a handful of emerson with titanium liner locks. none have ever flexed or rolled or had any rock. on harder cutting ive had the lock bar seat deeper and stay deeper permanently. same is true on steel liner locks I've used on harder cutting. harder meaning cutting sugar cane as an example. which a fixed blade is the proper tool to use.

id expect spyderco would do it better or right.
 
Gen 4 xm 18 used a lot never a problem

Spyderco southard used a lot never once an issue, same for a spyderco chokwe
